Here,

For Ur Information...

SURD is a number that can't be simplified to remove a square root.

Now,

Coming Back to ur question...

Answer 2

Answer:

30

Step-by-step explanation:

=√20×√45

=4.47213595×6.70820393

=30

______________________________

alternative:

=√20×√45

=√20×45

=√900

=√30×30

=30

surd is a number that can't be simplified into a whole number( a number without fractions or decimals) after taking square root and hence √20×√45 is not a surd

I hope you understand this
